影响电子皮带秤计量误差的因素很多,其中重要的因素之一,是托辊上粘有泥土等脏物带来的误差。托辊上粘有泥土,不仅能使皮带行走不平稳,而且相当于给计量加了一个虚重,计量不能反映真实的重量。在选厂作业条件下,托辊往往很容易粘上泥土,如不及时清除,将带来不良效果。为此,我们进行了改进,这一改进是在托辊旋转方向的侧面各装上一块刮板(附图),使其起到刮泥作用。 There are many factors that affect the measurement error of the electronic belt scale. One of the important factors is the error caused by dirt and so on adhering to the roller. Roller on the sticky soil, not only make the belt walking is not smooth, and the equivalent of adding a dummy to the measurement, measurement can not reflect the true weight. In the operating conditions of the election plant, the roller is often very easy to stick to the soil, if not promptly removed, will have adverse effects. To this end, we have made improvements. The improvement is to have a scraper attached to each side of the roller in the direction of rotation (figure) so that it acts as a scraper.
